Discover precision astronomy like never before with the Pegasus Astro NYX-101 Strain Wave Gear Mount. Achieve unparalleled tracking accuracy and smooth motion for your celestial observations. Designed for astronomers by astronomers, the NYX-101 offers exceptional stability and versatility, ensuring your telescope captures breathtaking views of the cosmos. Elevate your stargazing experience with this advanced astronomical gear mount, perfect for both seasoned astronomers and newcomers to the night sky.

Strain wave drive on RA and DEC movement ensures a backlash-free operation with high torque at high payloads. A fully CNC machined aluminum alloy 6061 body, black and blue anodized, and a selection of branded parts (stepper motors, strain wave gear) inside the mount, ensure that Nyx-101 will perform flawlessly for many years. Mount includes an electronic brake on the RA axis to prevent backsliding when power is off as well as safety limit stops during slew or tracking.

Harmonic Gears on Both Axis ensure high payload and a smooth, backlash-free operation.

A hybrid combination of a stepper motor & belt system along with sophisticated electronics can drive the RA axis down to 0.10 arcseconds of resolution

Reduction on the RA axis is 500:1 and 300:1 on the DEC axis.

Counterweights are not required for weights up to 20Kg.(counterweights can be installed for higher photographic loads)

Lightweight Design, compared to the payload of weight the mount can lift

CNC-machined aluminum alloy AL6061 used for aircraft makes the mount an excellent choice for your setup.
Mount weights 6.4 Kg

From a small refractor to a fully loaded SCT 11-inch telescope, NYX-101 can easily handle the payload

Mount can be used as a German Equatorial mount or as an Altazimuth, more suitable for visual observations

NYX-101 supports wireless and USB 2 connectivity out of the box.
Both technologies can work simultaneously.

Mount is compatible with LX200 protocol and Sky Safari for mobile interaction

A safety power-off brake is installed on the RA Axis and provides an instant safe stop
during a planned or unplanned power interruption.
